block
to
extend
the
width.
CAUTION
When
a

with
slings
for
haulage,
take
into
consideration
the
offset
of
its
gravity
center
position.
If
not

•
Deliver
the
unit
as
close
as
possible
to
the
installation
site
before
removing
it
from
the
packaging.
•
When
you
have
to
unpack
the
unit
for
a
compelling
reason
before
you
haul
it
to
the
installation
point,
hoist
the
unit
with
nylon
slings
or
ropes
and
protection
pads
so
that
you
may
not
damage
the
unit.
•
The
right
hand
side
of
the
unit
as
viewed
from
the
front
(diffuser
side)
is
heavier.
A
person
carrying
the
right
hand
side
must
take
heed
of
this
fact.
A
person
carrying
the
left
hand
side
must
hold
with
his
right
hand
the
handle
provided
on
the
front
panel
of
the
unit
and
with
his
left
hand
the
corner
column
section.
(1)
If the unit is installed in the area where the snow will accumulate, following measures are required. The bottom plate of unit and intake, outlet may be blocked by snow. 1
Install the unit on the base so that the bottom is higher than snow cover surface.
Since drain water generated by defrost control may freeze, following measures are required. •
Do not execute drain piping work by using a drain elbow and drain grommets (accessories). [Refer to Drain piping work.]
2
Install the unit under or provide the roof on site.
Be
careful
of
the
following
conditions
and
choose
an
installation
place.
•
Where
air
is
not
trapped.
•
Where
the
installation
fittings
can
be
firmly
installed.
•
Where
wind
does
not
hinder
the
intake
and
outlet
pipes.
•
Out
of
the
heat
range
of
other
heat
sources.
•
A
place
where
stringent
regulation
of
electric
noises
is
applicable.
•
Where
it
is
safe
for
the
drain
water
to
be
discharged.
•
Where
noise
and
hot
air
will
not
bother
neighboring
residents.
•
Where
snow
will
not
accumulate.
•
Where
strong
winds
will
not
blow
against
the
outlet
pipe.
•
A
place
where
no
TV
set
or
radio
receiver
is
placed
within
1m.
(If
electrical
interference
is
caused,
seek
a
place
less
likely
to
cause
the
problem)
•
If
a
operation
is
conducted
when
the
outdoor
air
temperature
is
–5
o
C
lower,
the
outdoor
unit
should
be
installed
at
a
place
where
it
is
not
influenced
by
natural
wind.
•
Where
it
is
likely
that
the
unit
is
subjected
to
strong
winds,
provide
wind
guards
according
to
the
following
guidelines.
Strong
winds
can
cause
performance
degradation,
an
accidental
stop
due
to
a
rise
of
high
pressure
and
a
broken
fan.
4) Caution about selection of installation location
•
Walls surrounding the unit in the four sides are not acceptable.
•
There must be a 1-meter or larger space in the above.
•
When more than one unit are installed side by side, provide a 250mm or wider interval between them as a service space. In order to facilitate servicing of controllers, please provide a sufficient space between units so that their top plates can be removed easily.
•
Where a danger of short-circuiting exists, install guide louvers.
•
When more than one unit are installed, provide sufficient intake space consciously so that short-circuiting may not occur.
•
Where piling snow can bury the outdoor unit, provide proper snow guards.
•
In installing the unit, fix the unit’s legs with bolts specified on the above.
•
The protrusion of an anchor bolt on the front side must be kept within 15mm.
•
Securely install the unit so that it does not fall over during earthquakes or strong winds, etc.
•
Refer to the above illustrations for information regarding concrete foundations.
•
Install the unit in a level area. (With a gradient of 5mm or less.) Improper installation can result in a compressor failure, broken piping within the unit and abnormal noise generation.

be
perpendicular
to
the
